... or, even a rocket scientist can understand DNS
The goal of this page is to help you make sure that your DNS is set up properly,
and help you many common errors that may exist. It will also help you if you are
setting up DNS for the first time -- there is a lot of valuable information in
here, and after you are done, you can walk through this step-by-step to make
sure you did everything properly. Just go through the following steps in order:
- Step 1: WHOIS: Making sure you exist at the top of the food chain.
- Step 2: Your Name Servers: 1 primary, at least 1 secondary, identical to what WHOIS reports.
- Step 3: SOA Record: The beginning (and end) of your DNS entry.
- Step 4: A Records: Turning domain names into IP addresses.
- Step 5: MX Records: Making sure mail gets delivered to you.
- Step 6: CNAME: Pointing to someone else's servers.

That should cover most common errors. For a more comprehensive way to check
your DNS, you may want to check out www.DNSstuff.com
and www.DNSreport.com. For other cool tools using past DNS data, check out www.DNStrails.com.
